They need the i18nCoverage attribute added to show up in the list. I fixed the "Populate i18n" button that shows up in the upper-right dropdown in the level editor, which adds this and the i18n attributes automatically now, so we can use that.

Specifically Covered is whether the language you're translating in has translated all the fields in the target document.

Generally Covered is whether any language in the same family (like zh-HANS and zh-HANT) has translated all the fields. It's on my TODO list to not display "Generally Covered" for languages with only one language in the family, because it's not any different from Specifically Covered.

It looks like Lost Viking has your translations properly in there now; not sure what happened.

Got the levels. Dungeons of Kithgard Complete is actually named "The Journey Begins" for legacy reasons. I don't know what's up with the red errors on those achievements, but your translations were saved. I have accepted the patch for the How Old Are You poll that you successfully submitted despite the error message.

There is already an issue open for "Problem III" in GitHub.I've repopulated i18n in Sarven Savior, so it is now possible to translate Overview and Overview body.I also opened an issue on GitHub for "Problem V".
